In the Kat Speculation thread users have begun tracking the days she works as implied by Phil and events in the background. Last I looked, it was estimated she was working three days a week. If she was any kind of valued employee, you'd think the effort to transfer her from MI to WA would mean she works more hours. OTOH, if she was a troublesome hourly widget, those fuckers get passed around companies like herpes. If she was a pain to work with, and asked to transfer out of the district, they'd gladly make Khet someone else's problem. I see that scenario more than the gold-digging demon lady also being put-together enough to be nationally flexible management at Kohls. And in that case, it would explain fewer days at work, and not more, especially during the most important months of retail sales.
Taking everything Phil says as mostly lies with a bit of truth, my guess is the "transfer" really meant "I told her find a part time job out here and then I'll confirm your plane ticket." If she actually did transfer within the company, she was still so low on the totem pole (part time associate, I'm thinking), it would have been the same if she applied as an outsider. No benefits or anything. The same process they use to get rid of the guy that steals out of everyone's coats without having to do the termination paperwork.
Phil's greed was too strong not to demand Khet find a job before she even got there. On her end, she didn't move in with him to work, so she does the bare minimum. Phil being a spineless slug, can't confront her and tell her to work more, but she can definitely demand more money from him, and I think that's happening behind the scenes.
